The trouble with articles like the HotRod Hotline one, is it is written by yahoos that are not as careful as us yahoos try to be..
...Folks are paid to write an article, they read a bunch of web bits and pieces, some of which is wrong and repeated over and over, and they put it all together in their own professional writing words...and it gets all screwed up..
Similarly here on this forum and others not everything posted is correct.
The end user should always consider that and do their own research (beyond the forum) coming to their own understanding and conclusions.
Perhaps best we can do is site sources for hopefully more reliable info to support the opinions and understandings we try to share here.
